On Sunday, President Barack Obama and Republican Mitt Romney raced through battleground states, seeking a breakthrough in a close race. In New Hampshire, Obama told thousands of cheering supporters, "You have the power."

Romney told supporters in Cleveland that instead of Obama "bridging the divide, he's made it wider." He also stopped in Yardley, PA outside Trenton--and praised Governor Chris Chrstie for giving "all of his heart and his passion" to help his state recover from Sandy. Christie, meanwhile, told reporters he is still voting for Romney on Tuesday despite Obama's support for New Jersey's recovery efforts.

'5 Ohios' analyzed in swing state

Ohio could well decide the next president.

The state has chosen the winner in the last 12 presidential elections, and it's pivotal to the strategies of both President Barack Obama and Mitt Romney.

The Ohio winner has usually done particularly well in his party's traditionally strong areas, and better than expected in other regions.

The state's geography is often divided regionally as the "Five Ohios" — the northeast, northwest, central, southeast and southwest parts of the state.

Obama needs to pile up votes in northeast Ohio, the state's Democratic stronghold, anchored by Cleveland and the industrial towns of Youngstown and Akron.

Fla. remains tough sell to end for Obama, Romney

Florida is proving to be an expensive and frustrating state for President Barack Obama and Republican Mitt Romney, right down to the campaign's final minutes.

Its voters resist arguments that play well in Ohio and other places. Both nominees are making stops in Florida in the campaign's final 40 hours.

Florida is a tough sell for Obama's national message of steady economic recovery. Its unemployment and foreclosure rates remain above the national average.

And auto industry ads airing in Ohio would make no sense in Florida. But a well-organized Democratic ground game and a population that's increasingly non-white have given the president hope of winning Florida narrowly.
